Having spent hours pouring over scientific expositions of the silent sermons of the starry hosts, I first want to put my hand over my mouth. I want to say with Job that far too often “I have uttered what I did not understand, things too wonderful for me, which I did not know” (Job 42:3). I fear trivializing what is ineffably profound.

“When I look at the stars, I see someone else.” (Switchfoot)

When David looked up in the Near Eastern night sky 3,000 years ago, what he saw almost took his breath away. And in an attempt to express the wonder that flooded him as he contemplated his minuteness in view of such vastness, and God’s design in it all, he did something uniquely human: he transposed his awe into art.

When I look at your heavens, the work of your fingers, the moon and the stars, which you have set in place, what is man that you are mindful of him, and the son of man that you care for him? (Psalm 8:3–4)

The “heavens,” that mysterious realm of marvelous lights, have astonished mankind from our earliest days. When we look at the heavens today, our understanding of what we see, due to advances in science and technology, far exceeds David’s understanding. David only had a hint of how minute he was in relation to the heavens. Our fuel for awe is astronomically greater. We know more, but do we marvel more?

Silent Sermons of the Stars

The starlit sky is speaking. In Psalm 19, which C.S. Lewis considered “one of the greatest lyrics in the world” (Reflections on the Psalms), David again wrote,

The heavens declare the glory of God,

     and the sky above proclaims his handiwork.

Day to day pours out speech,

     and night to night reveals knowledge.

There is no speech, nor are there words,

     whose voice is not heard.

Their voice goes out through all the earth,

     and their words to the end of the world. (Psalm 19:1–4)

If the heavens are the work of God’s “hands,” and if they are declaring the glory of God, what are these silent preachers telling us? To listen closely, I have leaned on David Blatner’s book, Spectrums: Our Mind-Boggling Universe from Infinitesimal to Infinity to help capture the wonder of what we too often take for granted.

All That We (Do Not) Know

When David surveyed the sky, part of what he saw belonged to our solar system (sun, moon, and a couple “stars” that were really planets), part belonged to our Milky Way galaxy, and part were distant stars and (probably) other faraway galaxies. David would have barely had a clue how massive and distant these heavenly bodies were.
